Petunia plant named ‘Duepotpiwi’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Duepotpiwi’, characterized by its compact and outwardly spreading to trailing growth habit; freely branching habit; early and freely flowering habit; medium-sized white-colored flowers; and good garden performance.

Botanical designation: Petunia×hybrida.

Cultivar denomination:‘Duepotpiwi’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petuniaplant, botanically known as Petunia×hybrida and hereinafter referred toby the name ‘Duepotpiwi’.

The new Petunia plant is a product of a planned breeding programconducted by the Inventor in Rheinberg, Germany. The objective of thebreeding program is to create new compact Petunia cultivars withnumerous attractive flowers.

The new Petunia plant originated from a cross-pollination made by theInventor in August, 2006 in Rheinberg, Germany of a proprietaryselection of Petunia×hybrida identified as code number T05-0840-010, notpatented, as the female, or seed, parent with a proprietary selection ofPetunia×hybrida identified as code number F-03-23, not patented, as themale, or pollen, parent. The new Petunia was discovered and selected bythe Inventor as a single flowering plant within the progeny of thestated cross-pollination in a controlled greenhouse environment inRheinberg, Germany in May, 2008.

Asexual reproduction of the new Petunia plant by terminal cuttings in acontrolled greenhouse environment in Rheinberg, Germany since May, 2008,has shown that the unique features of this new Petunia plant are stableand reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment and cultural practices such as temperature andlight intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Duepotpiwi’. These characteristics incombination distinguish ‘Duepotpiwi’ as a new and distinct cultivar ofPetunia:

-   -   1. Compact and outwardly spreading to trailing growth habit.    -   2. Freely branching habit.    -   3. Early and freely flowering habit.    -   4. Medium-sized white-colored flowers.    -   5. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parentselection. Plants of the new Petunia differ primarily from plants of thefemale parent selection in flower size as plants of the new Petunia havesmaller flowers than plants of the female parent selection.

Plants of the new Petunia can be compared to plants of the male parentselection. Plants of the new Petunia differ primarily from plants of themale parent selection in plant size as plants of the new Petunia aremore compact than plants of the male parent selection.

Plants of the new Petunia can be compared to plants of thePetunia×hybrida ‘Duesurwi’, disclosed in U.S. Plant Pat. No. 13,829. Inside-by-side comparisons conducted in Rheinberg, Germany, plants of thenew Petunia differed primarily from plants of ‘Duesurwi’ in thefollowing characteristics:

-   -   1. Plants of the new Petunia were more compact than plants of        ‘Duesurwi’.    -   2. Plants of the new Petunia were more freely branching than        plants of ‘Duesurwi’.    -   3. Plants of the new Petunia had smaller leaves than plants of        ‘Duesurwi’.    -   4. Plants of the new Petunia were more freely flowering than        plants of ‘Duesurwi’.    -   5. Plants of the new Petunia had smaller flowers with shorter        peduncles than plants of ‘Duesurwi’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Petunia, showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Petunia plant.

The photograph comprises a side perspective view of a typical floweringplant of ‘Duepotpiwi’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurementsand values describe plants grown in Rheinberg, Germany, under commercialpractice during the spring in a glass-covered greenhouse with day andnight temperatures averaging 18° C. and light levels averaging 4,500lux. Rooted young plants had been growing for 16 weeks when thephotograph and description were taken. Plants were pinched one timeabout three weeks after planting.
